. j IMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent No. I 83,393, dated October17,1876; application filed July 10,1876.

To all whom it may concern:

Be it known that I, GEORGE T. Hnnig'icK, of Mill Springs, in the countyof Wayne and State of Kentucky, have invented a new and Improved Plowand I do hereby declare that the following is a full, clear, and exactdescription of the same.

My invention is an improvement in the class of sod or turning plows andrelates, first, to the construction of the stock, wherebyit is adaptedfor attachment of right and left shares and mold boards; second, to theconstruction of said shares and mold boards, whereby they are adaptedfor such attachment; and, third, to the provision of an adjustablewheel, which is so attached to the heel of the plow as to adapttit to beswung under the latter to support it while being drawn or propelled fromone place or field to another.

In the accompanying drawing, forming part of this specification, Figure1 is a side elevation of the plow, with a part in section. Fig. 2 is aplan View of the under side of the plow proper. Fig. 3 is a front viewof the double share and mold-board. Fig. 4 is a vertical section on linea: m, Fig. 3. Fig. 5 represents different views of the L-shaped brace.Fig. 6 represents the T-shaped brace. Figs. 7 and 8 are detail views ofplow-stock.

Apart from the beam and handles A B B, the frame of the plow consists,mainly, of the curved flat standard 0, extended forward and terminatingin a triangular point, a, and the land-side plates D, which are attachedto the rear extension I) of the standard by means of bolts or othersuitable devices. The standard 0 has a number of bolt-holes and a lug,d, the latter being located on one side, immediately in front of the endof a land-side plate, D. These said holes, the lug, and the point a ofthe standard, together with the shoulders or bearing-surfaces formed bythe ends of the land-side plates, constitute the chief features of theconstruction of the stock, whereby the share and mold-board are firmlybut removably attached, as will presently appear. The share andmold-board may be constructed double, as shown in Figs. 3 and 4', toadapt them for reversal, as required for hill-side plowing, or the samemay be of the ordinary form,

as shown in Fig. 2, and made either right or left. In either case theconstruction of the parts whereby the attachment to thestock of the plowis effected is substantially the same that is to say, a plate, E, isattached to the under side of the share and mold-board, and serves toconnect one to the other. This plate has a vertical flange or wing, c,which is notched on the rear side to receive the lugd of the standard 0.The flange 6 lies parallel to the vertical barf formed on the inner sideof the share or point. 7

When the share and mold-board are applied to the stock, as shown inFigs. 1 and 2, point a of the standard 0 enters between the flange e ofplate E and the bar f of the share, and a bolt is passed transverselythrough them all, to lock them securely together. The vertical rearsides 'or edges of said flange and bar likewise abut the ends of theland-side plates B, while the lower edge of the remaining bar or flangerests upon the upper edge of the inner one of said plates B, and issimilarly secured to the standard 0 by means of bolts. By thisconstruction the share and mold-board are securely attached to thestock, but may be conveniently and quickly removed and readjusted orsubstituted by others, as occasion requires.

The brace F- for supporting the mold-board has an .L or T shaped head,according as it is required for use in connection with the single rightor left share, Figs. 1 and 2, or the double share, Figs. 3 and 4. Ineither case the lug or arm 2' which forms the head enters a socketformed between the land-side plates, and no bolt or other supplimentaryfastening is required to secure it in place. The brace is hence adaptedto be readily detached or adjusted in position on either side of theplow. The colter H has a horizontal shank, I, through which passes thebolt that secures it to the standard 0, and the lower end of the colterrests against the share and mold-board, so as to be supported by themwhile cutting the sod. By this mode of constructing and attaching thecolter some material is saved, and the colter is less liable to bebroken than when attached to the beam. The wheel I, by which the entireplow is supported when being drawn or propelled from one point or thusassists to hold the arm K steady. When i. i

the Wheel is not required for useyth'e'armis swung up in a positionnearly parallel to the handles, between which the wheel passes and issecuredby a hook,-m*, as"s=h-own.=

This device is applicable to various kinds of plows, and may be pivotedto other parts of the plow than the heel of the land-side.

I do not'claim; broadly; theattachmentof a baringwhc'el toa plow in suchmanner as to 1 adapt it to swing under and support What I claim is-' 1.The plow-standard O,=havingthe point a and lug d, and-provided with theseat hav-" ing the notched vertical flang e as shown andtdescri'liedi y22 The combinationof thestandard ()with double land side, mold-board,and share, as

"shown and described.

3. The curved or bent arm K, carrying the bearing-wheel and pivotedtothe land side plates, as shown and described, for thepurposespecified..

4. The bent arm pivoted tothe heel of the land-side, the bearing-wheel,pivoted to the free end of said arm, the hook m, and the liaudlesB;extended below thebeam; as shown iand idescribed, whereby the wheel maybe secured in the elevated position, as specified. 1
